Journal ArticleDOI
Hierarchical Coordination of a Community Microgrid With AC and DC Microgrids
TL;DR: The simulation results verify that the proposed hierarchical coordination strategy is an effective and efficient way for coordinating microgrid flows in an islanded community microgrid, while maintaining the rated frequency and voltage with each microgrid.
Journal ArticleDOI
DC Microgrids: Economic Operation and Enhancement of Resilience by Hierarchical Control
Liang Che,Mohammad Shahidehpour +1 more
TL;DR: Case studies in which an existing microgrid at the Illinois Institute of Technology (IIT) is operated as a dc microgrid are provided and the results for each case are compared with the ac model, which demonstrate that the proposed coordinated dc strategy for the optimal operation of DERs is an effective way of ensuring the resilient response to emergencies and its economic operation at steady state.
Journal ArticleDOI
Optimal Interconnection Planning of Community Microgrids With Renewable Energy Sources
TL;DR: The numerical results demonstrate that the proposed interconnection planning methodology will determine an optimal topology accurately and efficiently for a cluster of microgrids, and show that the suggested adaptive planning methodology can easily be applied to practical microgrid applications.
Journal ArticleDOI
Only Connect: Microgrids for Distribution System Restoration
TL;DR: In this article, the authors highlighted the importance of reinforcing the electricity infrastructure and the need for further investments in more comprehensive data communication and distribution management systems, distributed energy resources, energy storage facilities, additional automation, and further migration toward decentralized operations for the largely centralized power grid.
Journal ArticleDOI
Adaptive Protection System for Microgrids: Protection practices of a functional microgrid system.
TL;DR: In this article, the authors proposed a distributed energy resources (DER) integration to reduce transmission losses and enhance the operation reliability of distribution systems, where DER penetrations representing bidirectional power flows and topology-dependent fault currents could affect protection devices, cause danger to the maintenance personnel, and result in uncontrollable undervoltage and frequency.
